Thrust fault hanging wall.

Generally when the fault dips less than 45 it s called a thrust fault steeper faults are called reverse faults. Thrust faults are reverse faults that dip less than 45. Reverse dip slip faults result from horizontal compressional forces caused by a shortening or contraction of earth s crust. Diagram showing how one section of land slips over another in a thrust fault.

The difference between the two faults is the angle of the fault. Thrust faults typically form ramps flats and fault bend hanging wall and footwall folds. A thrust or a reverse fault is a dipping fault whose hanging wall is translated up dip. The hanging wall moves up and over the footwall.

This is not however a hard and fast distinction. Other articles where thrust fault is discussed. According to mechanical models of. Flat segments of thrust fault planes are known as flats and inclined sections of the thrust are known as ramps.

A thrust fault has the same sense of motion as a reverse fault but with the dip of the fault plane at less than 45. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing. Thrusts are commonly low angle faults. Thrust faults with a very low angle of dip.
